CHICAGO, ILLINOIS.

EQUALIZER AND SEPARATOR FOR STEAM.

To all whom it may concern:

Be it known that I, DAvro M. STOTT, a citizen of the United States,residing at Chicago in the county of Cook and State of Illinois, haveinvented a new and useful Equalizer and Separator for Steam, of whichthe following is a specification.

The objects of my invention are 1st. To hold back the rushing of thewater with the steam out of a steam boiler, which occurs frequently,leaving the boiler empty and allowing it to become super-heated while atthe same time there is no steam pressure, as shown by the safety valve.Then when the water returns and comes in contact with the super-heatedboil er, it vaporizes so rapidly that the safety valve is unable to takecare of it and the result is an explosion.

2nd. To separate the water from the steam before it reaches the mainnozzle connecting to the heating system, engine, pump or other deviceusing steam.

3rd. To form a safety device so that if a rush of water should takeplace it would be stopped until the water level was equalized in theboiler, and at the same time forcing the steam pressure back into theboiler where it would be relieved by the safety valve if too great.

4th. To act as a blow-off to remove any oil that may have collected inthe boiler, which collecting on the to of same is so detrimental to themaking of steam and the proper working of the boiler.

This device may be applied either inside, or outside of a boiler, and Ido not confine myself to the particular form or arrangement shown inmaking my claim as it is obvious that this might be modified or changedand still not depart from the spirit of the invention which is when, forany reason the water is inclined to flow out of the boiler with thesteam to check the passing of either water or steam fromthe boiler untilan equilibrium is maintained and the water level established.

I attain these objects by the device illustrated in the accompanyingdrawings of which Figure 1 shows a side elevation in connection with theordinary water column and steam gage of a steam boiler with parts brokenaway to show construction. Fig. 2 is a cross section taken on the line2-2 Fig. 1. Fig. 3 is a similar view showing the baflie plate lifted upagainst the cover.

Specification of Letters Patent.

Application filed April 30, 1908.

Patented Oct. 27, 1908.

Serial No. 430,056.

Similar letters refer to the same parts in the several figures.

Let A represent the main body of the device with a flanged opening a atthe bottom connected to the supply pipe from the boiler a The body A hasa flange a around the top, bolted to which is the cover A having in itscenter a flanged opening a for connecting with the pipe for conductingthe steam' wherever it is to do its work.

It will be noticed the cover has a portion of its width A depressedthroughout its length for a purpose to be explained later on.

Inside of the chamber A is a baffle plate B which divides the chamberinto two parts 1 and 2. This plate rests upon flanges or studs 6 whichare formed on the inside walls of the chamber A, along its length,integrally with the side walls. The plate B has openings b b for steamto pass into the chamber 1, so arranged as to direct the steam towardthe center of the de ressed portion of the cover, along its lengt 1. Theeffect of this is to de fleet the steam from its course up throughopening a allowing any of the water of condensation to fall on the plateB. This plate is formed as a pan to catch this drip and allow it to passout through one small opening. The end walls of the pan 6" are shaped tofit the depressed portion of the cover at its ends when the late israised up as shown in Fig.

3. The sides of the plate are arched along its length forming domes ccfrom which the openings 12 6 lead.

The opening 12 is suflicient to take care of the little water ofcondensation which may accumulate in the pan but not suflicient topermit any great volume of water which might rush up with the steam andif not prevented would be forced into the pipes be yond. When such anaction occurs the water, coming in contact with the broad surface of thebaffle plate B willraise it off the flanges b-b into the position shownin Fig. 3, bringing the holes I) 5 against the curve of the sunkenportion of the cover A closing them completely allowing neither waternor steam to pass further.

After the flow is stopped and the ressure directed back into the boilerto be taken care of by the safety valve, the natural tendency of watertoseek its level would pause it to flow back into the boiler, either bythe pipe D connected with the water column D or through the supply pipea After the water commenced to return in this way the small opening I)in the bottom of plate B would relieve any tendency to form a vacuum inthe pipes beyond. The plate B would return to its normal positionallowing the steam to pass up the supply pi e through a The usual steamgage D is s own over the top of the water column.

Between the chamber A and the water column D in the ipe D is a valve Dwhich when there is oi on the water in the boiler can be opened to drawofl the same without emptying the boiler.

Having thus described my invention,- what I desire to claim and havegranted by Letters Patent is- 1. In a steam separator and waterequalizer, a casing provided with inlet and outlet passages, and abafiie plate interposed between said passages in position to be moved bythe inrush of water and provided withan opening adapted to be closed bythe movement of the bafile plate, due to the inrush of water, andprovided with a port suitably positioned to remain open during allmovements of the baffle plate, substantially as described.

2. In a steam separator and water equal izer, the combination of acasing rovided with inlet and outlet passages, ant a baflie plateinterposed between said passages and positioned to be lifted by theinrush of water, and provided, near its periphery, with a hole adaptedto be closed by the lifting of the baffle plate, and provided, near itscenter, with a port adapted to remain open during all movements of thebaffle plate, substantially as described.

3. In a steam separator and water eq ualizer, the combination of'aeasing rovlded with inlet and outlet passages, anc a baffle plateinterposed between said passages and adapted to be lifted by the inrushof water, and provided, near its periphery, with a hole adapted to beclosed by engagement of the I baffle plate with the wall of the casingwhen the baflie plate is lifted, and provided with a port adapted toremain open during all movements of the baffle plate, substantially asdescribed.

4. In a steam separator and water equalizer, the combination of a casingprovided with inlet and outlet passages, a baffle plate interposedbetween said passages, and provided, around its periphery, with abackwardly turned edge, and provided, near said edge, with a holeadapted to be closed by engagement of the baffle plate with the wall ofthe casing when the plate is raised, and provided, near its center, witha port adapted to remain open during all movements of the baflie late,substantially as described.

5. n a steam separator and water equalizer, the combination of a casingprovided with inlet and outlet passages, the wall of the casing adjacentthe outlet passage being inwardly dished to provide a boss, and a bafiieplate recessed in its center and provided on its edge with a pair ofbaekwardly turned lips or flanges, and having, near its edges, a pair ofholes adapted to be closed by engagement of the baffle plate with theboss around the discharge passage, the baffle plate being furtherprovided, near its center, with a hole adapted to remain open during allmove ments of the baffle plate, substantially as described.

6. In a steam separator and water eq ualizer, the combination of acasing provlded with inlet and outlet passages, and a baffle plate ofrecessed construction, provided with a port for the passage of steam andtheoutflow of water of condensation, said baflie plate being adapted tobe moved by the inrush of water, substantially as described.
